A non-fluorinated polymer processing aid composition comprises an organo-modified siloxane, a synergist, an antioxidant, and a carrier resin. The composition may be useful for improving polymer processing during film production by reducing sharkskin and die buildup.

The present invention provides a reaction mixture comprising a hot blend of a first isocyanate-based uretdione resin and a second isocyanate-based uretdione resin, a neutralized polyol and a tertiary amine catalyst, and optionally, an additive package selected from the group consisting of flow control additives, pigments (colorants), wetting agents, and solvents, wherein the first isocyanate and the second isocyanate are different. The isocyanate-based uretdiones that have been hot blended together produce coatings, adhesives, castings, composites, and sealants, which exhibit better performance properties (such as microhardness) than those coatings, adhesives, castings, composites, and sealants produced from the constituent isocyanate-based uretdiones alone.

The present invention provides a reaction mixture comprising a polyuretdione resin, a neutralized polyol, an acid-blocked tertiary amine catalyst, and optionally, an additive package selected from the group consisting of flow control additives, and wetting agents, and solvents, wherein the acid has a pK.sub.a of greater than 4.82. Compositions made from the reaction mixture of the present invention may be catalyzed at temperatures from room temperature to 130 C. and are particularly applicable in or as coatings, adhesives, castings, composites, and sealants with good performance and extended pot-life.

The present invention provides a system comprising an allophanate composition comprising a neutralized polyol, a polyuretdione resin, a tertiary amine catalyst, an additive package, and a reducer; and a neutralized basecoat comprising an inorganic salt and a pigment. The present invention further provides a method of making an allophanate system comprising combining a neutralized polyol with a polyuretdione resin in the presence of a tertiary amine catalyst, an additive package, and a reducer to produce an allophanate composition, and contacting the allophanate composition with a neutralized basecoat comprising an inorganic salt and a pigment. The system may be used to make coatings, adhesives, castings, composites, and sealants in which clear-coating on neutralized pigmented basecoats is much improved in comparison to coating on non-neutralized basecoats.

The present invention provides an allophanate system made by a method comprising combining a neutralized polyol with a polyuretdione resin in the presence of an optional reducer to produce a one-component allophanate composition, and contacting the one component allophanate composition with a basecoat comprising a tertiary amine catalyst. The inventive allophanate system is particularly applicable in providing coatings, adhesives, castings, composites, and sealants with good performance.
